You can see the way those prices of cryto are fluctuating earlier this year the price of btc was close almost $40 but due to the economy problem and some others factors it as make the price to be affected not only on btc but on cryto in general and this effect is still creating unstable till this very moment.

as for the price of btc at the end of the year, if everything return back to normal their are probability that the btc price will be be between $39 to $40 which I believe is still very okay

I believe by this alot of losses will be recovered and many will be will to sell part if their btc which can also affect the price again,what did I mean by this is that when the price goes higher it would stay too longer before it get reduce again because if the was many that have btc before now will be willing to sell out
